Resumen:

The suprachiasmatic nucleus (SCN) transmits its rhythm by precise anatomical connections that release peptides and amino acid neurotransmitters. The SCN uses at least four different types of neuronal targets in the hypothalamus to pass on its circadian signal: (1) endocrine neurons; (2) pre-autonomic neurons; (3) structures that dissipate the circadian signal within and outside the hypothalamus; and (4) areas outside the hypothalamus. The SCN has a major role in organizing metabolism and diminishing the effect of stress. The relationship between the different hypothalamic functions and the SCN is discussed. Hereby special attention will be given to how a disturbance of our daily balance in activity, sleep, and food intake may lead to obesity and diabetes. © 2009 Elsevier Ltd All rights reserved.
